Major problem with kelp everywhere - trying to stay in deep water. Half an hour of furious work with chart, plotter and pencil transferring a string of waypoints to the computer - Cook had the same problem but he did not have a chart and sent Discovery ahead to find a way through.
Bright sunlight again - snow on Presqu'ile de la Societe de Geographie and Cook Glacier just visible behind it. We could not have picked a better day - so far!
Could be a long day - we both have to stay awake but opportunities between waypoints for one or other to grab half an hour if we get lucky.
